The speed unit looks more like knots than mph.

I'm not so sure. The same data packet claims that the flight has 2h 25m of flight time left to cover 1167 miles. That works out to 483 mph, which is pretty close to the stated 487 and might be explained by some padding added to the time to account for taxiing. Unless that 1167 figure is in a different unit it doesn't even come close to working out at 487 knots ground speed.

I used to do the same thing at hotels. Still often works. nmap -sn 192.168.0.1-255 To find everyone on the network, then start spoofing each of their MACs until you find one that works

I should probably know the answer, but what happens when two devices have the same MAC address?

this seems to be a decent answer written up ready to go.

what happens depends on your LAN setup, but generally its a fail.

When my son was younger - maybe 9 or 10 or so, we were on a plane and he was using his phone and I looked over his shoulder and realized he was on the internet... but I hadn't paid for an internet plan. I said, "son, how are you using the internet?" He said, "oh, a kid at school showed me - if you go here" (he opened up the wifi settings where the DHCP assigned IP address is) "and start changing the numbers, eventual…

A few years ago I was on a Southwest flight and had OpenVPN running because I forgot to turn it off. I was able to access the Internet through my tunnel without paying for access. I guess at the time they were only port blocking common ports (80, 443, 53 etc) if you didn't pay. They have since closed that hole.

No way to tell for sure, but I can only assume that he had actually hijacked somebody else's connection and the other person's device stopped working for them. I sure wasn't going to stand up and ask the plane if anybody had had their internet plan hacked...

Buy a plan then clone the mac of that device, white hat it. Might have killed a bit of time (unless you needed sleep) :)

A plane going up and down 20-30 feet seems like it would be very unpleasant. Considering that there's longitude and latitude, isn't it more likely that the altitude is coming from GPS, which is notoriously inaccurate with regards to elevation?

20-30 feet change over what timeframe? The resolution of the chart data in the article is about 30 seconds. While I think the fluctuation is due to the accuracy of instrumentation, 20-30 feet change over the course of a minute seems like nothing.

That's significantly slower than a typical elevator, in fact. Slow elevators run at about 200 feet per minute.

Ha! I've used a high-end GPS to see my location and other fun facts in flight. I learned to keep it in my pocket as despite my attempts to explain it was only a receiver, I was told by the flight attendant to "PUT IT AWAY." Not being one to push back as to be removed for that flight, I did just that. Streets and Trips was fun on a laptop for long car drives as you could live reroute in the car much like any old app c…

FAs can be really strange about that kind of stuff, not just out of ignorance. My kid liked to suction cup his GoPro to the window to take a time lapse movie of the flight and one FA told him he had to take it off the window because he was, and I quote: "modifying the structure of the aircraft and that's not FAA-approved".

Probably just didn't want kid spit on the window.

The plane is measuring altitude , which is relative to a reference point, unlike elevation which is relative to sea level. And if the altitude is determined by pressure sensor, musn't it be relative to the ground directly below the plane, anyway? (Although personally, I agree with the sibling comment that the variability is likely an artifact of the sensor resolution.)

Planes dont measure height relative to the ground. How would that even work? Their sensor is air pressure, which is treated as a function of elevation.

They do sometimes! Via radar altimeters, when relatively close to the ground. And sometimes to keep autopilots from freaking out, we have to build radar reflectors to make the ground look level to radar even when it's really not. https://lustublog.com/2017/02/17/artificiel-mais-pas-superfi...

How does that fly (pun intended) with regards to net neutrality? Where I live, some mobile operators gave you "unlimited streaming" in their data plan, but only for certain popular services (spotify, youtube, netflix basically). Since this would make it harder for others to disrupt the big ones, it was quickly forbidden.

Is net neutrality even law anymore? T-Mobile has had Binge on for a long time, which zero-rates certain video streaming services. And part of that was even under the old net neutrality laws.

Net neutrality is the law in California, but T-Mobile says Binge On is ok because any video streaming service can participate for free. It sounds reasonable to me and apparently the California regulators are fine with it.
